Using RC oscillator we can shift the phase of a Sinusoidal signal. In this image, there are two AC sinusoidal signal wave presented, the first Green Sinusoidal wave is 360 degree in phase but the red one that is the replica of the first, read signal is 90 degree out of the green signal’s phase. We will understand phase shift in the next image. If we shift the sinusoidal wave starting point other than the 0 degree the phase is shifted. Now without further delay let’s see what phase shift is? Phase is a full cycle period of a sinusoidal wave in a 360 degree reference. If we see the above sinusoidal wave like this one we will clearly see that the signal’s starting point is 0 degree in phase, and after that every peak point of the signal from positive to 0 then again negative point then again 0 is respectively denotes as 90 degree, 180 degree, 270 degree and 360 degree in phase position.
